Resistance to Flow in a V-Shaped Bottom Channel

Water flow in open channels is always subject to the resistance to flow and energy dissipation. For design purposes, one of the needed variables is the hydraulic resistance coefficient. For this mean, the influence of cross-sectional shape together with secondary flow cells and lateral distribution of true boundary shear stress have not yet been fully explored. This paper surveys the number of ...

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Local and Global Friction Factor in a Channel with V-Shaped Bottom

This paper presents an experimental research on the distribution of local friction factor, fb, and global friction factor, f, over the cross-section of a channel with V-shaped bottom, which typically occurs in sewers and culverts. Several series of experiments were conducted for measuring velocity and boundary shear stress. It is found that, Darcy-Weisbach, f, is more sensitive than other resis...

Star-Shaped and L-Shaped Orthogonal Drawings

An orthogonal drawing of a plane graph G is a planar drawing of G, denoted by D(G), such that each vertex of G is drawn as a point on the plane, and each edge of G is drawn as a sequence of horizontal and vertical line segments with no crossings. An orthogonal polygon P is called orthogonally convex if the intersection of any horizontal or vertical line L and P is either a single line segment o...

Stress Distribution within the Rotator Cuff Tendon with a Crescent-shaped and an L-shaped Tears

INTRODUCTION: There are various shapes of full-thickness rotator cuff tears, but they are mainly categorized into two types; crescent-shaped and L-shaped tears. Although it is widely accepted that the tear often propagates with time, the exact propagation pattern in each type of tear is still remains unknown. In the present study, we attempted to clarify the stress distribution in the tendons w...
